A prerecorded message saying you've won a free cruise to the Bahamas. All expenses paid. lol.
Not FREE And calls at least three times a day. If you can block. it block it. The first time you take the call you will be placed on the calling list and then your number gets sold to other jerks who don't give to shits about you unless you give them money. I recommend that you just don't take the call and block it after they stopped the call. Not even someone you can yell at.
